Abstract
Active upper G-I bleeding cases were divided into 3 groups, 45 cases were treated by Nd-YAG laser, 13 cases were treated by argon laser and 41 cases as the control group were treated by nonendoscopic methods.
Bleeding was stopped for over 72 hours in 42 cases (93%) treated by Nd-YAG laser, in 10 cases (77%) by argon laser and in 26 cases (63%) by control methods.
The mean blood transfusion volume in severe cases was 1490 ml in the Nd-YAG group, 2070 ml in the argon group and 5050 ml in the control group. In moderate cases 560 ml in the Nd-YAG group, 930 ml in the argon group and 2290 ml in the control group.
In moderate cases the rate of surgical operations which were performed within a month in the Nd-YAG grout was 7%, in the argon group was 11% and the control group was 38 %.
Using argon laser, bleeding from exposed blood vessels the diameters.of which were over 1.5 mm could not be stopped.
